Jark Wu commented on FLINK-31464: --------------------------------- I would suggest using Timo's approach proposed in FLINK-31368, because most SqlNodes are not maintained in the Flink repo, and we can't make them extend some converter interface. > Move SqlNode conversion logic out from SqlToOperationConverter > -------------------------------------------------------------- > > Key: FLINK-31464 > URL: https://issues.apache.org/jira/browse/FLINK-31464 > Project: Flink > Issue Type: Technical Debt > Components: Table SQL / Planner > Reporter: luoyuxia > Priority: Major > > Similar to FLINK-31368, the `SqlToOperationConverter` is a bit bloated. We > can refactor it to avoid the code length for this class grow quickly. > We can follow the idea proposed in FLINK-31368. > -- This message was sent by Atlassian Jira (v8.20.10#820010)
